ELECTRIC LAMP.

Application led April 11, 1922. Serial No. 551,443.

To @ZZ who-m t may concern.'

Be it known that I, GUY W. COMER, a citi- Zen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful improvements in Electric Lamps, of which the following is a specification.

My invention relates to a new and useful improvement in electric lamp; and more particularly to a railway lantern; and has for its`0bject to provide such lamp with means connected to the supportingelement thereof for conveniently closing and opening the electric circuit of said lamp.

Cther objects will appear hereinafter.

The invention consists in the combinations andarrangements of parts hereinafter described and claimed.

The invention will be best vunderstood-by reference to the accompanying drawings forming a part of this specification, and in which,

Fig. 1, is an elevational view of my invention;

Fig. 2, is a vertical section taken through the casing of the lamp; v

Fig. 3, is a detailed view of an insulating member;

Fig. 4, is a diagrammatic view of the electric mechanisms;

Fig. 5, is a sectional view of the lantern handle, showing the circuit open;

Fig. 6, is an enlarged view thereof, showing the circuit closed;

Fig. 7, shows a modified form of hand grip and circuit maker and breaker;

' Fig. 8, shows a section taken through line 8 8 on Fig. 7;

Fig. 9, shows a cross section taken through line 9 9 on Fig. 7;

Fig. 10, shows another modified form of hand grip and circuit maker and breaker;l

Fig. 11, shows a cross sectiony taken through line 11-11 on Fig. 10; and

Fig. 12, is a horizontalsectional taken on line 12-12 of Fig. 2.

The device comprises a casing or housing 14, which may be constructed of metal or other suitable material and made in any suitable shape; said housing is provided with a top 15, and with standards 16 fastened beneath its bottom 17. A metallic bar 18 extends from the pivot bolt 19 at handle 20 down toward the bottom 17, is bent and extends over said bottom, and is again benti to pass down into an insulated sleeve`21 view ` fastened on the bottom 17 to form the outer contact member 22 for the electric light 23. Another metallic member or bar 24 extends from the other pivot bolt 19 of said handle down'toward thebottom and extends a distance over said bottom. A fibrous insulating ring 25 is placed between said bars and the inner side of said housing and an insu- Ilating disc r26 is placed between the horizontal portions of said bars and the bottom 1.7 of the housing; while an insulating disc 27 is placed upon said horizontal portion of the bars and carries a metal ring 28, which is electrically connected by means of a pin f29 with the bar 24.

A suitable battery 30 is positioned in the housing; one contact member 0r pole 31 engaging the ring 28, while its second contact member or pole 32 engages the head 33 of a pin 34, which contacts with the inner terminal of light 23.

rlhe pivot bolts 19 and 19 have their heads engaging the inner sides of bars 18 and 24; but are insulated from the housing by means of fiber washers 35 shown in detail in Fig. 3) through which said pins pass, said washers being provided with angular necks 36 which engage inr similar angular openings in the housing. Fiber washers 37 are placed between the outside of the housing and the loops 38 of the handle,

while nutsv 39, which are threaded on the ends of the pivot bolts 19 and 19, engage the outer sides of said loops and press them against the insulating washers 37.

The bail handle 20, which supplies the ymeans for supporting the lantern while in use, is composed of metal or other lsuitable material adapted to conduct an electric current, and is constructed in two similar, separate parts, one of which is provided with a right-hand thread on its upper end 40 and the other with a left-hand thread at is upper end 40, said threaded ends engaging in/suitable threads in a tube or hand grip 41, which is composed of ber or other suitable insulating material, an angular nut 42 is fastened on the handle, and a finger 43 is fastened on said grip to` hold the grip from turning until positively actuated by the hand. f

The' upper ends 40 and 40 of the handle are normally held apart, as shown in Fig. 5, leaving the circuit open as illustrated diagrammatically in Fig. 4, and to close the electriccircuit thehand is slightly turned llO Y thereby rotatingthe hand gripr` 41 to bring the hand the ends 40 and 40 together, 4as shown in F ig. 6, to close the circuit, whereupon the' light 43 is illuminated, the current passing from the battery through its polev32, through pin 34, light 23, member 22,"bar 18, pivot bolt 19, handle 2Q and its ends40hand pivot bolt 39, bar 24, pin" 29, ring' 28, and through the pole 31, back into the battery. The nut 42 and finger. 4? ,"vvilll retain grip and itsele'ctric switch in said position'. i

In Figs. 7, 8 and 9 is shown a modified form of circuit closing means or hand grip, Which comprises a stein 45er insulating materialin the end portions; of which tvvo smooth upper ends 46fo'fl`v the bail'l'iandle are seen and held by finetal pins. 4'( having heads/48 which are simultaneoiis'lylengageable fby 'lugs '49 on] metal 'bari 50, said metal'bar is, slidable in a Agroove"formed on stem 45 and isfprovidedrwi'th `ringenlugs 51, and' a sleeve 5,2 surreunds and i`s`fas tened on stem 45 and retainsthe barf50 in position. y

By manipulatingeithei fingering. 51, the lugs 49 or bar 50 may bel broughtinto contact With heads 48 of pins 47 to complete the circuit With said bar 50, betweenV the ends 46 of the bail handle," l

In Figs. 10and 11 is shown another modified form of hand grip or circuit closing means, which comprises a stem 54 of insulating material, in which stem theends 55 of the bail handle are held by metal pins 56 passing through the ends and extending to a semi-circular groove 57 provided `on the metal portionl of said stem. A sleeve 58 surroundssaildmetal portion of the stem, covering said groove 57i-,anda curvedplate 5 9 is fastened to said sleeve with a screw 60 andl may be moved in said groove by. rotating saidr sleeve to engage both of said pins '.56 in-the ends 55 of the bail handle tocompletethejcircuit through the` ends 55. y

It is evident that inthe forms shown in Figs. 1 to 6 and.: inflffigs. 10fand `11, the

light.may. be energized by. ai slight movement ofthe hand which carries` the*A lantern, thereby. turning the respective sleeve il or 5,8,Whille in the form shown in Figs, 7,8 and v9A a` merei `outward movement of thee-linger or thumb of theJ engaged hand yWill-factulate thelig'ht Without the use ofthe other hand Vand Without the use of. any. fsivitch on the/ body of thel'antermfas isx commonly.. in
